I can agree with it, but I think it would be a great feature. And it
doesn't depends on Perl 6, but it depends on Parrot, as I think.

"&kilobytes := &kilobyte;" will not work for you (try it), because you
have to declare the "variable" kilobytes - in the default strict mode.
But you can't say for ex. "my &kilobytes", if you want to export it. I
would like to copy if the subroutine/variable is local, or exported,
or... etc. Oh, I have the term: I would like to copy the _scope_ of it,
too. Forget the "context". Simple binding shouldn't have to copy the
scope, too.
Anyway, "alias" is a Ruby term, and if Parrot will be able to support
Ruby, then it will be able to support this function, too.
Bye,
